The U.S. top envoy "is in the process of resigning" as ambassador, the embassy said in a statement.

The embassy did not give any reason for his resignation. U.S. President Donald Trump, however, said on Twitter last Friday that Hagerty will run for the senate in the state of Tennessee in 2020.

The embassy added that Joseph M. Young, deputy chief of mission, will be taking on the position of acting ambassador.
